.. HAT-SIZING MACHINE.

SPECIFICATION forming part of Letters Patent No. 565,498, dated August11, 1896. I Application filed August 29, 1895. Serial No. 560,915. (Nomodel.)

To (LZZ whom it may concern.-

Be it known that I, SEYMOUR G. PALMER,

a citizen of the United States, residing at South Norwalk, in the countyof Fairfield and State of Connecticut, have invented certain new andusefullmprovements in Hat- Sizing Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to certain new and useful improvements inhat-sizing machines, such as shown in Letters Patent of the UnitedStates No. 365,852, grantedto me July 5,1887, and has for its object theimproving of the automatic trip mechanism shown therein.

I-Ieretofore great difficulty has been experienced in properly fittingand adjusting the actuating-pawls which cause the rotation of theratchet-wheels shown in the above-mentioned Letters Patent, owing to thepeculiar sliding and rocking movement of the part which carries saidpawls, and when these parts had become worn by usageit not infrequentlyoccurred that the trip mechanism was rendered inoperative, necessitatingrepairs which were always more or less expensive. In my presentinvention I have improved the construction of these elements, so thatthey may be quickly and easily adjusted when the machine is first setup, and also all wear consequent upon long usage may be compensated forwithout removing any of the parts.

With these ends in view my invention consists in the details ofconstruction and combination of elements, as will be hereinafter fullydescribed, and particularly designated in the claim.

Referring to the accompanying drawings, which form apart of thisspecification, Figure 1 is a side elevation of my machine, illustratingthe automatic trip mechanism in both its engaged and disengagedpositions; and Fig. 2, a vertical sectional elevation on the line 0: xof Fig. 1.

As there are four vertically-sliding tables precisely alike on which thehats to be sized are placed and separated trip mechanisms for eachtable, a description of one of such mechanisms will be understood asapplying to all four.

Similar numerals and letters denote like parts in both figures of thedrawings.

1 is the frame, and 2 the power-shaft journaled therein.

3 is arock-shaft journaled in boxes at at the upper part of the frameand capable of a vertical sliding motion. Said rock-shaft is supportedby vertical connecting-bars 5, which are eccentrically connected to thepowershaft, so as to impart a slight vertical sliding motion to therock-shaft 3.

' 6 are oscillating hangers secured to the rockshaft and depending belowthe power-shaft, and 7 is the roughened upper sizing-surface, which isformed of slabs of wood secured to the lower rounded surface of saidhangers, so as to connect the same and cause them to move in harmony.

8 is a crank formed on the power-shaft 2,

and 9 isa sliding boxfitting within a vertical guideway (not shown) inone of the hangers 6.

10 is a belt-pulley rigid on the power-shaft, and 11 is a fly-wheel alsorigid on said shaft.

It will be evident from the foregoing that when the power-shaft isrotated an oscillating motion will be imparted to the uppersizing-surface, while at the same time a slight independent verticalsliding movement will be given said surface, as explained in the LettersPatent above referred to.

12 is a gate capable of sliding within ways 13 in the frame.

14 isa plate bolted to the gate and depending below the bottom of thesame.

15 is a foot-lever pivoted around a cross-bar 16 rigid with the frame.When this lever is depressed, the inner end of the same is adapted toengage the lower edge of the plate 14 and raise the gate to an elevatedposition.

17 is a sliding latch-bar, one end of which is loosely fitted within arecess 18 in the frame, (shown in dotted lines in Fig. 2,) while theother end is pivoted to a bell-crank lever 19, pivoted to abracket 20,rigid with said frame.

21 is a hand-lever pivoted to the frame at 22, and 23 is a vertical rodor link pivoted to said hand-lever at 24 and to the, upper arm of thebell-crank'lever 19 at 25. .The weight of this vertical rod or link 23and the upper arm of the bell-crank 19 is such as to cause the latch-bar17 to slide in the direction of the arrow, as shown in Fig. 2. A lug 26(shown in dotted lines in Fig. 2) is formed in the latch-bar 17, andwhen the gate 12 is elevated until the lower edge of the plate 14 isabove the plane of the latch-bar said latchbar will slide in thedirection indicated by the arrow thereon and bring the lug 26 beneathsaid plate, so as to hold the gate 12 in its elevated position. Toreturn the gate to its normal position, it is only necessary to pull onthe hand-lever 21, when the lug 26 will be withdrawn from under theplate 14, and said gate will drop by gravity.

27 is a table having aroughened sizing-surface 28, and 29 are verticalslide-bars, to which said table is rigidly secured. The bars 29 passthrough openings (not shown) in the cross-pieces 12 of the gate 12 andare guided vertically within said openings.

30 is a screw journaled in a boxing 31 and rigid with the gate 12 as toany independent lengthwise movement, but capable of a free rotarymovement.

32 is an X-shaped cross-piece bolted to the bars 29, and 33 is a nutrigid with said crosspiece 32, into which the threads of the screw 30take. It will thus be seen that by manipulating the screw 30 the table27 may be brought nearer to or farther away from the oscillating uppersizing-surface, so that a greater or lesser pressure may be exerted uponthe hats during sizing, as the character of the work to be performed maydemand.

a is a cord which passes over a pulley Z2, journaled on the frame, oneend of said cord being attached to the gate 12, while the other end hassuspended therefrom a weight 0, the object of which is to partlyretrieve the shock attendant upon the lowering of the table and also toassist the operator in elevating the same.

To relieve the operator of the necessity of giving his attention to thehat-roll during the time it is being operated upon by thesizingsurfaces, I provide automatic mechanism for tripping the table andallowing it to fall without the field of operation of the upperoscillating sizing-surface at any predetermined time.

33 is a ratchet-wheel journaled loosely on a short shaft 34, extendingfrom the frame.

35 is a pulley formed integral with the ratchet-wheel, and 36 is a cordattached to the periphery of said pulley, from the endof which a weight37 is suspended. 38is an idle pulley over which the cord 36 passes, soas to bring the weight 37 without the field of operation of other partsof the machine.

39 is a slide which works in bearings 40, bolted to the frame.

'41 is a pitman pivoted to the slide 39 at 42 and eccentricallyconnected to the powershaft 2, as is shown in dotted lines in thedrawings. The slide 39 is at its central portion threaded, as shown at43, and 44 is an arm having an opening 45, through which the threadedportion of the slide 39 passes loosely, said arm being held in properposition by nuts 46, which take on the screw-thread of the slide 39 andsecures said arm and slide rigidly together.

47 is a weighted pawl pivoted at 43 to the outer end of the arm 44. Theweighted lower end of this pawl exerts a tendency to keep the upper endthereof in engagement with the teeth of the ratchet-wheel 33.

49 is aweighted dog also pivoted at 48 and carrying a pin 50.

51 is a retaining-pawl pivoted at 52 to the frame, and having a finger53, which extends down and rests upon the back of the pawl 47 when thelatter is out of engagement with the ratchet. Projecting from the innerface of the ratchet-wheel is a pin 54. (Shown in dotted lines in Fig.1.) The object of this pin is to lift the vertical rod 23 by strikingagainst a lug 55, (shown in dotted lines in Fig. 1,) which projects fromsaid rod within the field of rotation of said pin, and thereby trip thelower sizing-table in the same manner as described in connection withthe hand-lever. This is accomplished bya step-by-step movement of theratchet wheel when the pawl is thrown into engagement therewith, whichis brought about by the elevation of the weighted dog 49 out of contactwith the pawl 47 by means of a pin 56, projecting from the gate 12 outthrough a slot 57 in the frame. Thus it will be seen that when the gate12 is elevated, as described, the pin 56, carried thereby, will relievethe pawl 47 of the weight of the dog 49 and allow said pawl, togetherwith the retaining-pawl 51, to go into engagement with the ratchet wheel33 by their weight. Now as the ratchet-wheel is actuated one tooth ateach oscillation of the upper sizing-surface, it follows that the hatwill be operated upon as many times as there are ratchet teeth betweenthe pin 54 on the ratchet-wheel and the lug 55 on the vertical rod 23before the table is dropped, and as their relative position between saidpin and lug may be varied by changing the stop-pin 58 to either of theholes 59 it will be seen that the desired extent of operation upon thehat-roll in its several stages maybe controlled automatically andwithout the care of the operator. When the bed is dropped by thewithdrawal of the lug 26 from under the plate 14, as previouslydescribed, the lowering of the pin 56 will permit the weighted dog 49 toexert its force upon the back of the pawl 47 and thus disengage thelatter, as well as the retaining-pawl51, from the ratchet-wheel, as

. seen by the position of parts at the right hand the position necessaryfor a repetition of these ITO movements upon the subsequent raising ofthe bed.

61 is a set-screw tapped in the arm 44, so as to bear against the slide39, the object of which is to prevent any turning of the arm upon saidslide.

The general features of the machine above described are shown in theLetters Patent previously cited, and I therefore do not wish to beunderstood as seeking to claim them at this time; but

What I do claim as new, and desire to secure by Letters Patent, is-

In a hat-sizing machine, the power-shaft, eccentric, and pitman, theslide connected to SEYMOUR C. PALMER. Vitnesses:
